Amanda Walters entered the construction industry with a mission to help people navigate one of life’s most personal journeys—the creation of their home. As the founder of OneStop ADU, she combines her financial expertise with hands-on construction experience to redefine what it means to build accessible, functional, and beautiful homes.
At OneStop ADU, it’s not just about building a house; it’s about creating a space that fits each individual’s needs. The company specializes in ADA-compliant homes, custom designs, and personalized service, making it a leader in the ADU market.
The Path to OneStop ADU
Amanda, originally from Dayton, Ohio, spent 23 years managing large government projects. With an MBA and experience in project management, she transitioned into construction, bringing a client-focused approach to building homes. As a licensed contractor (B and C-27), Amanda’s certifications ensure each project meets the highest standards.
Her philosophy is simple: the journey of building a home should be transparent and empowering. This dedication led to the founding of OneStop ADU, where every project is approached with care and attention to detail.
Challenges and Triumphs
Building a successful ADU business comes with challenges, but Amanda’s customer service sets OneStop ADU apart. From offering in-house showrooms for clients to select finishes to having real people answer the phone, the company emphasizes personal care.
“We treat every client like family,” Amanda says. “Whether it’s ADA compliance or accommodating a service animal, we ensure each home meets the unique needs of its residents.”
Amanda’s hands-on approach guarantees that no detail is overlooked, which contributes to OneStop ADU’s reputation for quality and customer satisfaction.
Redefining ADUs
OneStop ADU’s mission is to make ADU ownership accessible to everyone. The company’s expertise in ADA-compliant designs ensures that homes are not only functional but beautifully tailored to each client’s needs. Whether building a custom ADU or accommodating specific requirements, OneStop ADU creates spaces that reflect each homeowner’s vision while maintaining affordability.
“We help people realize their vision for their home,” Amanda explains. “Whether it’s a custom-designed ADU or an ADA-compliant unit, our goal is to make sure clients thrive in their new space.”
Award-Winning Excellence
OneStop ADU has recently been named Best Accessory Dwelling Unit Builders in California of 2025, a recognition of their commitment to quality, innovation, and customer satisfaction. This award highlights the company’s attention to detail and focus on providing accessible and affordable solutions in the competitive California ADU market.
“We are honored by this recognition,” Amanda says. “It reflects our team’s dedication and the trust our clients place in us to create homes that truly make a difference.”
Why OneStop ADU Stands Out

- ADA Compliant Design: Specializing in homes that cater to diverse accessibility needs.
- Community-Centered Leadership: Amanda’s commitment to local causes, such as K-9 Search and Rescue, extends beyond business.
- Award-Winning Expertise: Recognized as one of the Top 25 Most Influential Women in Construction for 2025.
